There are people who have learnt how to trade, practiced on demo accounts for long but have not had the money to try trading on the market, and so they have abandoned trading to try search for money first. While there are others who have too little income, that they cannot profit from the market trading, they are always worried about loosing and because of that they make mistakes with their technical analysis and end up loosing the little money they have. Should trading be exclusive to financially comfortable and rich because of how risky it is?
Trading is not always open for everyone, trading must have capital you cannot become dependent solely in trading if you don't have another source of income because sometimes if you want to grab an opportunity but you don't have money you will possibly just lose a chance to earn a huge amount. Seems trading must have money and knowledge once you lack one of these you will not become an effective trader.
